Abstract
The invention relates to a transverse feed type high-frequency quenching mechanism. The quenching mechanism is mainly characterized in that two pairs of rollers are arranged on the both sides of an induction coil which is arranged horizontally on the axis and a small shaft at the gap of each pair of two rollers and the inner barrel of the induction coil are coaxial. In addition, a corresponding squeezer is arranged above the small shaft, a roller which can contact with the small shaft is arranged on the lower end of the squeezer; a spring is arranged on the roller and the upper end of the spring is arranged on a support on the machine tool. The shafts of the two pairs of rollers are arranged on a bearing seat and the bearing seat is arranged on the transverse guide rail of the machine tool. Centers are arranged on the backs of one pair of rollers which can be provided with the small shaft. By adopting the quenching mechanism, each part of a workpiece can be cooled rapidly after heatedand the initial quenching temperatures of all the parts of the workpiece are the same, thus the quenching quality of the workpiece is ensured, the operation is simple and the work efficiency is high.
Description
Technical field the present invention relates to a kind of high-frequency quenching equipment, the high-frequency quenching equipment of particularly little axle class.
Background technology is present, and in the existing high-frequency quenching equipment, its main quenching mechanism is the ruhmkorff coil that links to each other with tuner.Quench axle type from the head end to the tail end through ruhmkorff coil by after the heating fully, just drop to quench liquid middling speed cold quenching.Its weak point is, needs whole axle all heated could speed cold, reduced the temperature before workpiece quenches so to some extent, and axle is type different in size, because the temperature variation before quenching is very big, and the just very difficult assurance of the quality of quenching.
Summary of the invention the object of the present invention is to provide the high-frequency quenching mechanism of the cold cross feed of induction heating limit, a kind of limit speed.The present invention mainly includes induction coil, roller, compactor and thimble.Wherein induction coil has two side faces that are nested together to be provided with the cylinder of axially open; The opening two ends of this inner/outer tube link to each other with two connecting plates respectively; Be the corresponding opening of inner/outer tube with linking to each other with a connecting plate, this two connecting plates extend outwards, respectively be located at lathe on tuner link to each other.Be provided with the annulus that opening is arranged that both folded gaps are sealed at the two ends of above-mentioned inner/outer tube.Above-mentioned urceolus is that bus is the straight tube of collinear, and inner core is that bus is the straight tube and truncated cone tube of broken line, and frusto-conical surface is provided with some through holes, i.e. fluid hole.On wall of the outer-rotor, be provided with fluid inlet in addition, it is preferably 1-4.Be provided with two pairs of slick rollers in the induction coil both sides of above-mentioned axis horizontal setting; Their axis all with the parallel axes of induction coil; Minimum clearance is less than processed little shaft diameter between every pair roller; So that little axle is placed on the gap of two rollers, be positioned at little its axis of axle and induction coil inner core axis coaxle on two roller gaps simultaneously.Above-mentionedly drive homodromal roller by adjustable frequency motor and can order about little axle and rotate; Above little axle, be provided with the compactor corresponding in addition with it; This compactor lower end establish can with the roller or the pressing plate that are coupling for a short time and touch; This roller or be provided with spring above the pressing plate, the upper end of this spring is located on the support above the lathe.The wheel shaft of above-mentioned two pair rollers is located on the chock, and this chock is located on the cross slide way of lathe, and roller can laterally be moved, and to adjust the spacing of two pair rollers, makes it the length less than workpiece.The above-mentioned roller that is equipped with little axle; One of which is provided with the thimble that promotes little axle axial advancement and pass induction coil to the rear portion; This thimble is located on the slide plate that has guide pin bushing, and this slide plate links to each other with ball-screw again, this ball-screw with link to each other by monolithic processor controlled servomotor.
Working process of the present invention is substantially as follows: with positioning between little pair roller (rear roller) that places thimble one side and the compactor.Little axle rotation under the drive of rear roller; It is moving that the thimble of simultaneously little axle back promotes little axial advancement again; Be introduced into the straight drum part of induction coil inner core,, move forward to inner core truncated cone tube part again by induction heating; Fluid hole on it then just has been heated part spray quench liquid to little axle, and little axle is quenched here.So little axle by after accomplish when advancing forward and quench.Little axle when quenching ceaselessly by the back to reach, the little shaft length that is positioned on the rear roller group is shortened gradually, and little axle front end is inserted between another pair roller (front wheel) and the compactor after passing induction coil, with little axle location.Little axle is located by the front wheel group fully when little axle breaks away from the rear roller group, thereby has guaranteed that little axis is coaxial with induction coil all the time.
The present invention compared with prior art has following advantage:
1, it is promptly fast cold that the present invention can make each heating back of workpiece, guaranteed that the initial temperature of quenching of workpiece each several part is identical, thereby guaranteed workpiece quenching quality.
2, workpiece is from the induction coil quenching of coming out promptly to accomplish, high efficiency.
3, the quenching workpiece need not be installed, and only by thimble workpiece is delivered to induction coil and gets final product, and is simple to operate, shortens process period.
